I run EUAE on my Intel Mac Mini. It can do it but, as has been mentioned, it is not as good as WinUAE. There's a lot of software for creative people on the Mac but they all have a price.
But the Mac OS can start Wondows from within OSX, right? At least it could do it before (and that was kind of cool). There you can use WinUAE. And while you are there, you can use the Windows version of Aladdin 4D instead of Mac. Heck, buy yourself a Win7 PC instead of Mac, Core-i7, with lots of RAM. It will be much cheaper than similar Mac system. Then buy the Mac (or whatever) version of Aladdin (the only way of getting the Windows version seems to be by buying some other version, and then you get the win version for free! :crazy:)
